C# - Proxy Pattern - Serialize A Class Into A String
May 10, 2011
I need to be able to serialize a class into a string, and I know of 2 patterns:
1) (normal) Serialization pattern
2) Proxy Serialization pattern
I've read [URL] (the only website in google that talks about the proxy-serialization pattern) and still cant find the advantage or benefit of using this pattern. Could someone explain what exactly is the proxy serialization pattern, or rather exactly what problem does the proxy-serialization pattern solves that the normal-serialization pattern doesn't solve?

CustomLineCap does not have the SerializableAttribute applied to it. I want to add a property of this type to an object graph that is currently being serialized/deserialized with a BinaryFormatter. I tried switching to XML serialization but it has a bunch of extra requirements and I don't want to fool with that esp. since it's not my code; it's some open source I downloaded. If there's a way to get BinaryFormatter to ignore the property, that might work. I'd rather subclass it; I just don't know if that will work either.

I am trying to figure out a class/struture to handle the following JSON format:
{
"ReturnData": [
{
"id": "msg2DoesNotExistName",
[Code]......
I may or may not have Data for ReturnData and SetValue (one or both at a minimum). I am trying to let the serializer handle most of the formatting without having to check for empty sections and single-item arrays.

I am trying to serialize a class that contains a generic list, and I am finding it all works with the exception of the generic list property. That is to say the other properties are serialized fine and no error is produced.
I have in the past serialized an arraylist - but I thought it was possible to do a generic list in the same way.
Am I missing something or is it not possible to serialize/deserialize a generic list - I have read mixed comments on this..
The relevant parts of the class that gets serialized is defined as..
<XmlInclude(GetType(cConfigUser)), _
Serializable(), XmlRoot(ElementName:="Config")> _
Public Class cConfig

I have a issue in a serialization process. I'm trying to Serialize a part of a bigger class.
I've a Class named MyBigClass with contain many property and method, and some of them may not be Serializable.
And I'm trying to Serialize one property of the MyBigClass class, witch is a SortedList named SubClassXList defined as SortedList(Int32, ClassX)
My problem is when it is time to serialize the SortedList (SubClassXList) a error tell me that a Class (say Class B) could not be Serialized because it is not marked as "Serializable", but the Class B in question have nothing to do with the SubClassXList in question.
The only thing I could see, is that the Serialization method try to also Serialize the Main Class (MyBigClass).
Here is the method that I use to Clone a Object ClassX do have the attribute "Serializable()"
Public Function CloneObject(ByVal pObjectToSerialize As Object) As Object
' Create a memory stream and a formatter.
Dim ms As New IO.MemoryStream()

I'm trying to serialize the main class in my VB solution. I've added the Serializable attribute at the top of my class like so:
[code]...
I'm guessing this is because you can't serialize the form that is attached to the class or something, but I really don't know what I'm doing. Can I serialize all of the objects contained in my Form1 class somehow, without getting this error? I don't want to store any data about the form controls, I just need to save all the objects that I've defined at the top of the Form1 class.

I have a VB.NET singleton class which implements Serializable:
Imports System.IO
Imports System.Runtime.Serialization
<Serializable()> Public Class CoordinateHistory[code].....
My problem is that I can't actually call .Serialize() on the instance of this class, like all of the examples online show. What am I doing wrong?

How best to manage multiple dat files for serializable objects of the same class. If one of my data files goes past a particular size, I want to create a new file. I then loop through both files when I do processing. Is there any easier way to do this and what's the best size to do this at in terms of performance?

I am a complete Newbie to VB.NET and am migrating up from VB4, so please forgive my mistakes.I am trying to create a proxy class using the WSDL tool included in Visual Basic 2008 Express Edition. I have managed to create the file successfully through WSDL tool, and then am able to add this file as an item in my VB project, however, the file that is added, comes up with 11 errors that I am not familiar with. The command I am using to create the file with WSDL tool is as follows:
wsdl /l:vb /protocol:soap http://direct.racetab.com.au/LiveOdd...gin/Login.wsdl This creates a file called Login, however it creates it, inside the folder that the WSDL tool is located in, which happens to be:Program Files/Microsoft SDKs/Windows/v6.0A/bin I then go to the solution explorer and right click the 'My Project' folder and select ADD>Existing Item, and then navigate it to the file that was just created.
This creates a new item in my solution explorer called Login.vb however, as soon as it is created, I get 9 errors and 2 warnings, that absolutely confuse the hell out of me, and all point to this new item 'Login.vb'
[Code]...
I am doing wrong, what I have forgotten to do, or how I can work to get around this problem? If I need to supply any more information, please let me know what you need to know. Also, if it helps, the only method that I plan to use from the above file is the GETKEY(userName, password) method.

I have been trying to generate a Proxy class in VB.NET using a WSDL file for an Apache Axis SOAP Web Service. They have provided me the WSDL file and when I use the WSDL.exe command (In Visual Studio 08) and point it to the local path I get an error.
wsdl /language:vb c:Orders.wsdl
(I am trying to create a .NET Client that consumes the SOAP Web Service Hosted on Apache Axis 2)
The Error
Unable to import binding 'OrdersSoapBinding' from namespace 'urn:company:orders:schemas:OrderTypes:1.00'.
-Unable to import operation 'placeOrder'
-The element 'urn:company:remtp:schemas:PlaceOrderRequest:1.00:PlaceOrderRequest' is missing
If I use the svcutil.exe I also get an error message...

I used wsdl.exe to auto-generate a proxy class, to post SOAP requests to a webservice. Works fine, but I would like to see the exact SOAP request my app is posting.
Is there a way to do this? Maybe a tool I can use?

I have a WCF Service exposing a single contract and operation:
<ServiceContract(Namespace:="ImageSystem")> _
Public Interface IUploadService
<OperationContract()> _
[Code].....
This subsequently leads to stream casting issues, because the generated function allows me to pass a memory stream as an input (which works correctly when passed through to the service), but instead of passing me back a new stream for the response, it attempts to cast the MessageBodyStream received from the service into my memory stream.
This is, in some ways similar to other posts but as you can see, there are no enums involved in my contracts - presence of Enums caused strange proxy class generation is marked as the answer in the similar post.
Is there anywhere I configure the proxy behaviour to use the contracts I've specified? Clearly I'm within a dev/test environment currently, but when this eventually goes to production it will be memory and file streams passed to the service, and the returned stream can be in any format to be honest, I intend to treat it as the abstract stream class. The only way round this I can see right now is to change my in stream to be the same as the anticipated out stream, but surely there is a better way?

I am struggling to extract a 'matched' string and wonder if I am missing something simple.Let's say my code finds a string 'abcdefgh -john. smith 1234567 a123-a-123-f the last search, abc, 123 ;'I am searching this string for the pattern '[a-z]###-[a-z]-###-*'I know this text appears in the string as 'a123-a-123-f'I would like to be able to return the matched string value 'a123-a-123-f' to a variable.If I place a wildcard * in front of the pattern, it will find the text, but obviously everything else in front of it, is there a way that somebody can think of to strip the variable without using the preceding wildcard?I am not worried about the wildcard on the end of the string as I can strip back to the last space.[code]

I have a networkstream (using C#/VB.NET). while on reading values coming like this:
&% 68 kg K A&% 23 kg K A&% 174 kg K A &% 68 kg
&% 34 kg K A&% 2334 kg K A&% 68 kg K A &% 68 kg K A
&% 2348 kg K A&% 78 kg K A&% 28 kg K A&% 68 kg
The numerical(weight) value will be continuously varying.
Every time i am reading the starting of the stream differs. But the pattern remains the same. How to split that into '&% 78 kg K A' which represents one set.
How to extract the weight value from this stream using Regex or any other methods?
